Tov a l/Z whom it may concern:

Be it known that I, CARL ADAMS, a subject ,of the German Emperor, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented new and useful Improvements in Devices for Automatically Stopping Looms, of which the following is a specification.

This invention relates to certain new and useful improvements in devices for automatically stopping a loom when the filling on the bob bin or filling-carrier contained in the shuttle has been exhausted to a predeter-' mined extent.

It is desirable to employ a device which will automatically stop the loom by means of a feeler coacting with the bobbin or quill or quill has been exhausted to such an extent that itwill be likely to run out at any time during the next few picks; and thereforeonc of the objects ofthe present invention is to produce a peculiarly-constructed device whi employs a minimum number of parts and not only'is durable, but comparatively inexpensive to construct.

Another object of the invention is the provision of means which is movably mounted upon a support and which is capable of st opping a loom when the filling upon a bobbin or quill has become partly or entirely exhausted.

With these and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts," as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the claims hereto appended.

' In the drawing the figure is a perspective view of part of a loom, showing my invention carried in an operative position thereby.

Referring to the drawing by numerals, 1 designates a suitable support, which maybe a part of the loom-frame, upon which is mount- .ed a horizontal movable member 2, retained upon the support 1 by anysuitable removable means-as, for instance, a bolt or screw 3. The screw 3 extends through a sleeve 4, formed integrally with the movable member 2'. The movable member 2 constitutes a supporting swinging arm, which is provided with parallel standards 5 5. The support 1 is provided with cut-out portions 6 and .7.

Within the cut-out portion 6 is. positioned avertical shippenhandle 8, the movement of which controls any suitable means for disconnecting the power and stopping aloom. The standards 5 5 carry a fixed horizontal shaft 9, which is provided with an integral head 10. A shaft 11 of the loom is provided with a weft-hammer 12, which is fixedly secured tosaid shaft. The upper end of the weit-hammer 12 is provided with a notched or cut-out portion 13.

An arm 14 is formed integral with the weft-hammer 12 and engages a cam or eccentric 15, fixedly secured to a shaft 16. The weft-hammer 12 and the arinld constitute an oscillatory member. The lay 17 carries the shuttle-box 18. A shuttle binder or holder 19 engages the shuttle 20, and an actuating-spring 21 engages the shuttle binder or holder 19. A bobbin or quill 22 positioned within the shuttle 20. The shuttle box or holder 19 and the actuating-spring 21 are provided with registering apertures 23 for permitting the feeler of my invention to normally project therethrough for engaging the bobbins 22. I The shuttle 20 is also provided with an aperture registering with the apertures Apicker-stick 24 coacts with. the shuttle-box 13. Most of the mentioned parts of the loom are known to the patented art and are only shown and described for the purpose of more clearly understanding the structure and application of my invention.

A bracket 25 is carried by the swinging arm. 2. The bracket 25 is provided with a vertical apertured extension 26. 27 is supported upon the vertical extension 26 within the aperture thereof. Sai dfeeler 27 projects through the registering elongated apertures 23 of the shuttle 20, shuttle-binder 19 and the actuating-spring 21. A horizontal revoluble rod or shaft 28 is journaled upon the parallel standards 5 5. Positioned upon the horizontal rod 28 and between the standards 5 5 are collars 29 and 30, each of which is provided with a setscrew 31. l A horizontal projection 32 projects from the inner standard 5, contiguous to the collar 29. The set-screw 31 is adapted to engage the projection 32 for limiting rotary movement of the rod 28 in one direction. A removable lug 33 is secured to one edge of the outer standard 5. A flexible member 34, preferably a coilspring, is secured at one end to the lug 33 and at the opposite end to the set-screw 31, which is'carried by the collar 30. The spring 34 holds the fee'le'r 27 against the bobbin 22. The set sorews 31 of the collars 29 and 30 are also employed for fixedly securing said col- The fer '[er IIO lars in an adjusted oosition upon the rod A removable and adjustable arm 35 is fixedly secured upon the ro( 28 by means of setscrew 36. Suitable fastening means, as rivet 37, pivotally ooi'inects the llattened apertured outer ends of the arm and feeler 27. A removable and adjustable crank-arm fixedly secured to the outer end of the rod 28 by means of a set-screw 39. The right-angled ortion of the crank-arm 38 is positioned within a substantially U-shaped member or portion 4-0, carried. by a dog or pawl-41, which is pivotally mounted at 42 upon the head 10 of the shaft 9.

The motion of the laycauses the bobbin or quill 22 to come in contact with the feeler 27, and if the bobbin is filled the arm will be swung outwardly and upwardly, thereby rotating shaft 28 and causing the crank-arm 38, through. the medium of the substantially U-sliaped member, to lift the pawl or dog 41 to the position shown in the drawings. When the bobbin is nearlyempty, the fecler 27 will,

not be pushed back far enough to cause the pawl or dog 41 to be lifted out of the path of. movement of the weft-l1ammer, which is actuated by the cam 25, and therefore the pawl or dog 41 will engage the notched. or cut-out portion 13 of the weft-hammer 12, and as the cam'15 lifts the arm 14, which is secured integrally to the weft-hammer 12, the movable supporting-arm 2 will be swung upon the support 1 and will push the shi 'i mr-handle 8, which controls any suitable means for throwing the loom out of operation.

The adjustabilitv of the arm 35, crank v arm 38, and the collars 29 and 30 permits of the devices to be adjusted to meet any 'desired requirement in reference to the size of the bobbin and. the filling carried thereby.
